# NOC case correction
> We get NOC from external financial institutions when the account details need to be changed (routing number / account number / account type etc). We create these NOC cases now which someone needs to act on (update the account with right information that we get from NOC and close the case). And based on new NACHA rules, we have to do this within 6 days.
The cases will show up here - [https://app.synctera.com/cases/list?caseType=payment\\\_alert\&status=active\&page=0](https://app.synctera.com/cases/list?caseType=payment\\_alert\&status=active\&page=0)
Steps:
Open the case
Look at the information that needs to be corrected and copy the corrected data
Click on the link ‘Original transaction’ and go to the external account
Click actions - > edit
Update the information as appropriate
Close the case.
